This code encapsulates the bit manipulation of STM32F2 series GPIO registers using unions and macros. The core design utilizes the RegSet union to facilitate convenient access to 32-bit registers and individual bits, while macros simplify the register address mapping for different GPIO ports (A-I). Below is the formatted code and an analysis of the calling … Read more
Opening of the C Language Micro Classroom Senior Students Assist in Breaking Through Learning Bottlenecks Event Content On the evening of November 8, the first lecture of the C Language Special Tutoring Course was held in the Computer College, Room S303, led by student Ruan Hongyi. He focused on topics such as binary storage and … Read more
1. Instruction Overview Starting from the Intel 80386 processor, the instruction set introduced a powerful set of bit manipulation instructions. These instructions allow programmers to precisely manipulate individual binary bits within operands, including operations such as testing, setting, clearing, complementing, and searching. This greatly enhances the efficiency and convenience of performing bit-level operations (such as … Read more
The C language is essential foundational knowledge in microcontroller development. This article lists some common basic knowledge of C language in STM32 learning. 01 Bit Manipulation Bit manipulation is different from bit-banding operations. Bit manipulation refers to performing operations on each bit of a variable, while logical bit operations are performed on the variable as … Read more
When assigning values to registers using the C language, bit manipulation methods in C are often required. Clearing a Specific Bit in a Register Assuming ‘a’ represents the register, which already has a value. If we want to clear a specific bit while keeping other bits unchanged, the code is as follows. // Define a … Read more
1. Base Conversion Data in computers is typically stored in binary form, but during programming and debugging, we often need to deal with decimal, octal, and hexadecimal systems. Therefore, mastering base conversion is an important part of learning C language. Editor 1.1 Basic Concepts of Number Systems Binary: Base 2, using digits 0 and 1. … Read more

Today I conducted an AD experiment and would like to share some insights. Using chips: ADC0832, 89S52 The circuit diagram is as follows: Today was my first time looking at the ADC0832 data sheet, and I was quite confused. I found a good piece of Chinese material on it. Actually, the timing diagram in the … Read more
Introduction: Recently, a certain country has imposed a series of restrictions and suppressions on us, such as banning the maintenance of semiconductor equipment and prohibiting the sale of high-end chips. This undoubtedly aims to hinder the innovative development of our AI and high-tech industries. As long as our artificial intelligence is integrated into manufacturing equipment … Read more
Scan the code to follow Chip Dynamics and say goodbye to “chip” congestion! Search WeChatChip Dynamics Dear “brick movers” of C language, today we will discuss something exciting—unions. If a structure (Struct) is a “luxury apartment” where each member has its own independent room, then a union is definitely a “shared rental house” where all … Read more
